Walking with Superman: Day 114

A few years ago, a portion of San Diego fell into the ocean, taking with it thousands of residents, who would have died if an induced genetic mutation hadn't made them into water-breathers. For a time, Aquaman protected the region, dubbed "Sub Diego" by its residents, until he was able to raise most of it above the waves and restore the populace. But hundreds were left behind even then, joined by many refugees from various disasters that affected Atlantis. When Aquaman disappeared for so long, they were left without any defense against the ocean wilderness. Now, Superman's journey brings him to the frontier town of Sub Diego, where the residents have found a new savior in the form of the sorcerer Ronal! His shape-altering enchantments have made him a hero to the undersea denizens, but Superman fears that Ronal's motivations are less altruistic than they seem.
